PTFE\PP\PE\PO lined steel tank, refers to the use of spray technology on coating of steel cans fluorine 0.01-3mm thickness, PTFE has anti adhesion, abrasion resistance, spray lubrication, antibacterial, clean, heat resistance, and corrosion resistance etc.. Widely used in various industrial fields: chemical industry -- the reaction tank, storage tank, heat exchanger, stirring rod, environmental engineering, waste gas treatment equipment, pipe fittings, valve, pump. The textile industry -- sizing roller, roller roller finishing, non-woven fabric. The electronics industry -- semiconductor factory fire smoke acid, printed circuit board electroplating rack. The food industry - baking equipment, baking, mold, all kinds of food processing machinery and parts electronic electroplating industry -- corrosion (printed circuit board with rack and fixture) semiconductor industry -- corrosion resistance, flame retardant (acid duct and parts).
PTFE F4 non stick coating can be used continuously at 260 degrees C, with a maximum temperature of 290-300 DEG C, very low friction coefficient, good wear resistance and excellent chemical stability.
Poly vinyl fluoride F46 or FEP: non stick coating in the baking flow of molten film to form a non porous film, with excellent chemical stability, excellent non stick characteristics, the maximum operating temperature of 200 degrees C.  
Teflon PFA PFA: nonstick coatings and FEP during baking melt flow formed without hole film. The advantage of PFA is that it has a higher continuous operating temperature of 260 DEG C, and it is more suitable for use in the field of high temperature resistance and chemical resistance.  　　
Teflon ETFE: is a copolymer of ethylene and tetrafluoroethylene, also known as the fluorine plastics, the resin is the most tenacious fluoropolymer, can form a coating layer of highly durable, excellent chemical resistance, and can work continuously at 150 DEG C.
After the product has been coated with fluorine, it has the following characteristics:
1, not sticky: almost all of the substances are not bonded with Teflon coating. Very thin films also showed good adhesion properties.  　　
2, heat resistance: fluorine coating with excellent heat resistance and low temperature characteristics. Short time high temperature to 300 degrees Celsius, generally between 240 DEG ~260 DEG can be used continuously, has outstanding heat stability, it can work in freezing temperatures without brittle, does not melt at high temperature.  　
3, sliding: Teflon coating has low friction coefficient. The friction coefficient varies with the load, but the value is only between 0.05-0.15.  　
4, the humidity resistance of surface water repellent: Teflon coating and oil production, the operation is not easy to stick with a small amount of solution, such as sticky dirt, simply wipe clean. Short time, save time and improve work efficiency.  　　
5, wear resistance: under high load, with excellent wear resistance. It has the advantages of wear resistance and non adhesion under certain load.  　　
6, the corrosion resistance of Teflon: almost no drug can protect the parts from erosion, chemical corrosion of any kind. PTFE is tetrafluoroethylene polymer. Abbreviated as PTFE. Brand name "Teflon or Teflon" (Teflon). The king of plastics". Teflon basic structure is used. - CF2 - CF2 - CF2 - CF2 - CF2 - CF2 - CF2 - CF2 - CF2 - CF2 -. PTFE is widely used in all kinds of needs of anti acid and organic solvent, which itself has no toxicity to human, but one of the raw materials used in the production process of perfluorooctane acid ammonium (PFOA) is considered to be carcinogenic. The relative molecular mass of PTFE is large, low for hundreds of thousands, high up to ten million or more, generally millions (degree of polymerization in the order of magnitude of 104, while polyethylene is only in the order of 103). The general crystallinity is 90 ~ 95%, the melting temperature is from 327 to 342. The CF2 unit of PTFE molecules in a zigzag shape arrangement, because the hydrogen fluorine atom radius is slightly larger, so the CF2 unit can not completely according to the adjacent trans cross orientation, twisted chains, but the formation of a spiral surface, the fluorine atom covers almost the entire polymer chain. The molecular structure explains the various properties of ptfe. When the temperature is lower than 19 DEG C, the formation of the 13 / 6 helix, the phase change occurs at a temperature of 19 DEG C, and the molecule is slightly untied to form a spiral of the 15 / 7. It at a temperature of 250 DEG C does not melt at -260 DEG C in ultra low temperature brittleness. PTFE smooth abnormal, even the ice than it; it is particularly good insulation, a thick newspaper film, it is sufficient to withstand the high voltage 1500V. PTFE polymerization of tetrafluoroethylene polymerization by free radicals generated by. The industrial polymerization is carried out in the presence of a large amount of water to disperse the heat of reaction and to control the temperature. Polymerization in general 40 to 80 DEG C, from 3 to 26 kg / cm under pressure of 2, available inorganic persulfate, organic peroxide as initiator, redox system can also be used. When the heat per mole of tetrafluoroethylene polymerization 171.38kJ. The dispersion polymerization is required to add a perfluorinated surfactant, such as perfluoro octanoic acid or its salts. The application of PTFE by compression or extrusion molding; also can be made into aqueous dispersion for coating, impregnated or made of fiber.
Teflon F4 in atomic energy, aerospace, electronics, electrical, chemical, machinery, instruments, meters, construction, textile, food and other industries as high and low temperature resistance, insulation and anti sticking coating corrosion resistant material, etc., are widely used
